“…TFM homes implement a well-specified model that utilizes proactive behavior approaches focused on promoting youth strengths, highly trained and supervised staff, ongoing professional consultation, and a focus on family-style living (U.S. Department of Health and Human Services, 1999;Wolf et al, 1995;Wolf et al, 1976). Many of the core TFM elements have been linked to positive youth outcomes (e.g., Friman et al, 1996;Gilman & Handwerk, 2001;Handwerk, Smith, Thompson, Spellman, & Daly, 2008;Handwerk, Turk, Hoff, Lucas, & Friman, 2006;Jones & Timbers, 2003;Larzelere, Daly, Davis, Chmelka, & Handwerk, 2004;Lee, Chmelka, & Thompson, 2010;Lee & Thompson, 2009;McNeal, Field, Handwerk, Roberts, & Friman, 2006). Much of this evidence, however, is either very dated or based on selected settings (Fixsen & Blasé, 2002;Kirigin, Braukmann, Atwater, & Wolf, 1982;Lazelere, Smith, & Daly, 1997;Thompson et al, 1996).…”
